Yes, George Washington did grow hemp...


...but not the kind you're thinking of.

Throughout his lifetime, George Washington cultivated hemp at Mount Vernon for industrial uses. The fibers from hemp held excellent properties for making rope and sail canvas. In addition, hemp fibers could be spun into thread for clothing or, as indicated in Mount Vernon records, used in repairing the large seine nets Washington used in his fishing operation along the Potomac.

At one point in the 1760’s Washington considered whether hemp would be a more lucrative cash crop than tobacco but determined wheat was a better alternative.

In May of 2018, Mount Vernon planted an industrial cultivar of hemp on the four-acre Pioneer Farm site. Under the 2015 Industrial Hemp Law enacted by the Virginia General Assembly and working with the industrial hemp research program of the University of Virginia, Mount Vernon planted hemp to expand its interpretation of George Washington’s role as an enterprising farmer. As the first historic home of the founding fathers to plant hemp, Mount Vernon will use the plant as an interpretative tool to help better tell the story of Washington’s role as a farmer.

Harvesting of the industrial hemp began on August 22 and will be used in fiber-making demonstrations onsite once it has been dried.

"I am very glad to hear that the Gardener has saved so much of the St. foin seed, and that of the India Hemp. Make the most you can of both, by sowing them again in drills. . . Let the ground be well prepared, and the Seed (St. loin) be sown in April. The Hemp may be sown any where. "

George Washington to William Pearce, 24 February 1794

Hemp, Canabis sativa is a plant originally from central Asia. It was cultivated with, and sometimes in place of flax because the stem fibers are similar. By the seventeenth century, Russia, Latvia, and other countries around the Baltic Sea were the major producers of hemp. It was from these areas Britain obtained its supply. However, during periods of military hostilities, the English had trouble acquiring enough hemp.

  • Rope made from hemp was vital to navies worldwide.
  • Hemp was used to make a coarse linen cloth, sacking, and other rough materials.
  • The oil extra of hemp seeds, like those of flax, was used in paints, varnishes, and soaps.

Washington's Use of Hemp

George Washington’s initial interest in hemp was as a cash crop. After deciding not to cultivate it as a cash crop, Washington grew it to meet the needs of his own plantation. Hemp was used at Mount Vernon for rope, thread for sewing sacks, canvas, and for repairing the seine nets used at the fisheries. Washington’s diaries and farm reports indicate that hemp grew at all five farms which made up Mount Vernon, (Mansion House, River Farm, Dogue Run Farm, Muddy Hole Farm, and Union Farm).

Cannabis sativa vs. Cannabis sativa indica

The type of industrial hemp grown at Mount Vernon is not the same cultivar of Cannabis used for recreational or medicinal purposes. Industrial hemp contains less than 0.03% tetrahydrocannabinol (THC) and therefore has no physical or psychological effects. Cannabis grown for recreational or medicinal purposes can contain 6% to 20% THC.

There is no truth to the statement that George Washington grew marijuana. His hemp crop was strictly the industrial strain needed for the production of rope, thread, canvas, and other industrial applications.
